WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent N 0. 442,150, dated December 9, 1890.

Application filed October 19, 1888. Serial No. 288,590. (No model.)

To aZZ whom it may concern:

Be it known that I, HENRY N. Swanrz, a citizen of the United States of America, re siding at Milton, in the county of Northumberland and State of Pennsylvania,have invented certain new an d useful Improvements in indoW-Screens, of which the following is a specificat-ion.

Myinvention has relation toiinprovements in window-screens of that character or class wherein the screen is held and arranged to slide in a frame formed with opposite beads or guides mounted at opposite sides of the windowframe and operated by the movements of the lower window-sash; and the object is to improve and simplify existin g mechanism now used for the purpose.

I have fully and clearly illustrated my improvements in the accompanying drawings, wherein- Figure 1 is a rear view of a window having my improvements attached, showing the sash down and the screen raised, one of the cords and pulleys being also shown. Fig. i. is a vertical sectional view showing the sash raised and the screen run down to close the open space. Fig. 3 is a front view in elevation showing the screen down and the arrangement of the cord thereon. l -ig. at is a view of the plate which holds the cord-pulley. Fig. 5 is a perspective of the cord-pulley and plate or bracket with connecting-lug. Fig. 6 is a side view of the cord-pulley. Fig. 7 is a dotail of the cord-adjusting spool.

Reference being had to the drawings, A designates the window-frame, 13 the upper sash, and C the lower sash, which are all of the usual construction and arranged in the usual manner. On both sides of the windowframe, at the rear of the upper sash and extending for the length of the window frame, are formed or secured beads or guide-strips 1, which engage with grooves 2 in the vertical sides of the screen'frame. The screen-frame 3 consists of a frame of the usual construction provided with a screen a stretched and secured to the frame, as may be desired, and the screen-frame is arranged, as indicated, to slide up and down on the beads or guides. To the lower rail of the screen-frame, at each corner thereof, is fixed a small staple or screweye 5, to serve as cord-guides, andin the middle of the screen-rail is mounted a small spool 6, to which the ends of the cords are fastened,

so that any slack in the cord may be taken up by turning this spool, or if the sash is not raised clear up the cords may be lengthened and the position of the sash to the screen regulated. As mentioned, the ends of the cords are fastened to the spool 6, and then run through the guides 5, and thence carried up over cord-pulleys 7 and have their other ends fastened to the lower rail of the lower sash. It will thus be seen that by raising the lower sash of the window the screen may be lowered accordingly, and that if it be desired to only partially raise the sash the screen may be lowered to the limit by giving it the requisite cord by unwinding that wound up on the spool 6.

8 designates a plate adapted to be secured, preferably, in the sash-channels of the window-frame. This plate is formed with a V- shaped slot 9, and when the plate is secured in place this slot is arranged over a cut-out space formed in the sash-channel or windowframe to provide space for the lug on the pulleybracket to enter and engage the slot. The pulley-bracket consists of a plate 10, formed with a -shaped holding-lug 11, the opposite walls of which are beveled inwardly to engage the slot in the plate on the windowframe, and a projection 12 on the opposite side of the plate, which has keepers 13 to hold the cord to the pulley, and on the projection 12 is a threaded hole, which takes the threaded end of the pintle-screw It, on which the pulley 7 is mounted, substantially as shown in the drawings. The plate 8 is countersunk in the sashchanuels or to the window-frame directly under the lower rail of the upper sash, with its outer face on a line with the surface of the window-frame or saslrchannels, so that when the pulleys are removed the upper sash may be run up and down, as usual, and the plates need not be removed when the screen is no longer connected to the windows.

The cord-spool (i on the lower rail of the screen-frame is held against turning in this instance by a binding screw 15, which serves also as the axis for the spool.

Having thus described my improvements, what I claim is- 1. The combination, with a window-frame having opposite guides and sashes, of a screenframe mounted for vertical movement in the guides, pulleys arranged intermediate the lower sash and screen-frame, and connecting, cords passing over the pulleys and having one of their terminals connected to the screenframe and their other terminal to the lower sash, whereby a sliding of the sash causes a similar though contrary movement of the screen-frame, substantially as specified.

2. The combination, with a window-frame having opposite guides and sashes, of a screenframe mounted for vertical movement in the frame, pulleys located intermediate thelower sash and screen-frame, and opposite cords mounted over the pulleys and having their inner ends connected to the lower rail of the lower sash and their opposite ends to the lower rail of the screen-frame, substantially as specified.

3. Thecombination,with the window-frame and upper and lower sashes of the window,a vertically-sliding screen arranged on guidestrips, and lifting-cords connecting the screen and the lower sash, of cord-pulleys to carry therlifting-cords, consisting of a plate formed with a slot, a pulley-bracket formed on a plate, having a lug to engage the slot of the plate on the window-frame, and a pulley mounted on the bracket, substantially as described, and for the purpose specified.

4. The combination,with the window-frame, opposite guides, and sashes mounted in the same, of pulleys located intermediate the lower sash and screen-frame and opposite cords passing over the pulleys and having their inner ends connected to the lower sash and their outer ends to the corresponding rail of the screenframe, and means for adj usting the cords so that the sashes may assume different relative locations, substantially as specified.

5. The combination, with a window-frame having opposite guides and upper and lower sashes, of a window-screen frame mounted for movement in the guides, pulleys located intermediate the lower sash and screen-frame, cords mounted in the pulleys and having their inner ends connected to the lower rail of the lowersash, and a spool projecting from the lower rail of the screen-frame and connected with the outer terminals of the cords, and a set-screw serving as the axis of the spool and to bind the same, substantially as specified.

6. The combination, with the window-frame, the upper and lower sashes thereof, the screen-frame, and the opposite cords connect- "ing the lower sash and screenframe, of opposite countersunk plates 8, secured to the sides of the frame between the sash and frame and having V-shaped openings, and pulley-brackets consisting of a bracket-plate 10 and rearwardly-disposed V-shaped lugs 11 for removably engaging the openings 9, and carrying pulleys 7 for supporting the cords, substantially as specified.

In'witness whereof I have hereunto set my hand in the presence of two attesting witnesses. V V
